Calysta’s “FeedKind” Replaces Fishmeal in Shrimp Feeds



At AquaNor, the world’s largest aquaculture technology exhibition (August 15, 2017, Trondheim, Norway), Calysta, Inc., an innovator in sustainable products to improve worldwide food security, announced that in a controlled feeding trial comparing fishmeal and its “FeedKind®” protein, the shrimp fed its protein ingredient had equivalent or higher survival and growth than those fed a standard fishmeal-based diet.  Calysta’s FeedKind protein is a family of natural, sustainable and traceable feed ingredients for livestock, fish, pets—and shrimp.




This was Calysta’s first trial with a warm water species and represents an entry into the six-million-metric-ton global shrimp feed market!  The trial was performed at Auburn University in conjunction with Texas A&M University, both located in the United States.


In the trial, Pacific white shrimp (Litopenaeus vannamei) postlarvae were fed a commercial control diet containing fishmeal as a primary source of protein.  Test diets were prepared where FeedKind protein replaced up to 100% of the fishmeal in the diet on a one-for-one basis.  The animals were fed either the control or a test diet for eight weeks in a controlled environment.  At the end of the study, shrimp survival was significantly improved in all FeedKind diets (93-97%), compared to the control diet (84%).  In addition, total shrimp weight in all FeedKind diet groups was shown to be equivalent to or improved, when compared to the control fishmeal diet.


“Shrimp remains one of the most valuable seafood commodities within aquaculture, with global trade of more than $20 billion per year,” said Ronnie Tan, a member of the Calysta Advisory Board and Vice President of Blue Archipelago, the largest shrimp enterprise in Malaysia.  “Innovative products such as FeedKind will be important new market entries as demand grows in emerging countries for new sources of protein.”


In September 2016, Calysta opened a “Market Introduction Facility” for FeedKind® protein in the United Kingdom.  Approved for sale in multiple countries, FeedKind is a safe, sustainable and a non-animal source of protein.  To produce it requires 77-98% less water and 98% less land than grain-based shrimp feeds.  Samples are currently available for global customers and partners in markets including the European Union, the United States, China, Japan, Southeast Asia and Australia.




Calysta has also announced a partnership with Cargill for the production of FeedKind Aqua protein in the United States.  Construction is underway on the first commercial scale FeedKind protein manufacturing plant in Memphis, Tennessee, USA, a venture formed in 2016 through investments from Cargill, Calysta and several third party investors.  The facility will be home to the world’s largest gas fermentation operation.


The plant is expected to produce up to 200,000 metric tons of FeedKind protein annually when completed and operating at full capacity.  Ground was broken on the 37-acre site in April 2017, and the first phase of construction is expected to be completed in 2018, with the plant coming online in 2019.  The second construction phase is expected to be completed in 2020.
